I've noticed over the last few thousand miles my z4 is less reluctant to rev over 5k ... it kind of hits a wall at that point and you have to change gear, the power drops off big time.
I watched some acceleration videos on youtube of 3.0is and they can zing round to the red line in a way mine just cant.
Has anybody had a similar problem and sorted it out? The car runs perfectly otherwise, only mod in drivetrain is a Remus backbox and I dont think it is that as its been on for ages.
MAF sensor maybe ?
